• Maintaining email authentication and reporting controls, including DMARC, DKIM, SPF and user phishing-reporting processes.
• Identifying and resolving email security assessment findings, configuration gaps and inappropriate exceptions in collaboration with internal teams and external specialists.
• Establishing practical operating procedures, dashboards, control evidence, KPIs and continuous improvement actions for endpoint, Microsoft 365 and email security.
• Using security incidents, phishing trends, audit observations, assessment results and user experience issues to develop sustainable improvements to security controls.
• Documenting remediation activities, assigning clear ownership and ensuring that actions are supported by appropriate evidence.
